Joom SEF and Magebridge Check/Config

Site Joomla 1.5.17 Magento 1.4.1 MageBridge 1.4.2 Disqus Kunena I have Joom SEF install 3.6.2. I keep getting a blank page when I enable it. I switched from SH404 today. I need SH404 cleaned out of the site. Someone that is proficient with this component. Can make my URL's better and give me more Google love. Magebridge, and Joomla updated today. Everythign is configured. I just need someone that knows the extension to come in and double check settings to make sure everything is correct. I can't get the root store to show but everything is installed correctly. 2 simple jobs for someone that has experience in these 2 components. I am available to help with whatever is needed. I am just new to Joom SEF and Magebridge can be a bit tricky. I think I just have a couple permissions wrong or something. If you can fix these quickly, bid and I will get you started fast. Power is out right now so I might have to wait till it comes back on before I can respond to bids.
